Abstract
Macleaya cordata (Willd.) (Papaveraceae) is used as an active component in the natural feed additive Sangrovit ®. Sangrovit ® contains mixture of the intact aerial parts and the fraction of quaternary benzo[ c]phenanthridine alkaloids from M. cordata (FQBA). In a 90-day pilot toxicity trial, Sangrovit ® and the FQBA were tested for safety. Male Wistar rats were fed for 90 days with 100, 7000 or 14000 mg of Sangrovit ® or 600 mg of FQBA in 1 kg of feed. Body and organ weights, clinical chemistry and hematology markers, oxidative stress parameters, morphological structure of tongue, liver, ileum, kidney and heart samples, and total cytochrome P450 in liver were monitored. The results showed no statistically significant alterations in any parameter between control and treated animals, except for the group treated with 14000 ppm Sangrovit ® that resulted in elevation of reduced glutathione level and superoxide dismutase activity in liver.
